Annotations are available only for java 1.5 and higher when creating the backend Google App Engine (JDK 1.8, new ADT)

Question

I installed the new ADT: http://developer.android.com/sdk/index.html?hl=sk Then I installed:

When I got into the readme directory of Eclipse, there are:

Eclipse Project Release Notes

Version 4.3.0 Last updated May 29, 2013

I created a new Android application, then right-click on it -> Google-> Generated the backend of the Google App Engine application, and this is what I got:

How to deal with this? EDIT:

Answer 1

I tried below and it helped.

• Check the Use default compliance settings box as in the highlighted section (blue color) of the image below.
• If this does not help, try changing the Compiler compliance level to another level, press the Apply key, and then again.

Answer 2

For me, the Enable project settings check box is not selected. I selected it and cleared the project through the Project menu.

Answer 3

The answer mentioned by Stultuske in [ eclipse magic: ... Syntax error, varargs is only available if the source level is 1.5 or more . >

On mac os x

• Install Java 6 JDK
• Go to Eclipse> Preferences
• Choose Add ... from Java> Installed JREs, then Standard Virtual Machine and select the directory /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home as the home JRE, then Done, Ok

Answer 4

Had a similar problem.

I checked the Java version of the JDK in the Java Build Path section.

I checked the match levels in the Java Compiler section.

I looked through Project Facets and saw that Java is not being tested. Checking this resolved the problem (after restoring the project).

Answer 5

make sure the source level is 1.5 or higher. it looks like you are using an older version of the JDK.
